Tatiana, these questions came up in normal conversations, not due to jealousy. Theses events with others, happened before we met.She has never cheated on me.
I just worry about what other lies she has told me.
I understand she was insecure about telling me of these previous meetings, for fear I would judge her a bad person.

If that is all it is, then fine.
but lies are lies, and they always cause damage.
